  specific image areas with easier access to all the tools for creating and
  editing nondestructive masks.

• Streamlined 3D painting and compositing
  Now paint
  directly on 3D models; wrap 2D images around common 3D shapes; convert
  gradient maps to 3D objects; and add depth to pixel layers, text, 2D shapes,
  and DICOM frames with volume rendering.

• Better raw image processing
  Enjoy superior
  conversion quality as you process raw images with the industry-leading Adobe
  Photoshop Camera Raw 5 plug-in, which now offers localized corrections,
  post-crop vignetting, TIFF and JPEG processing, and support for more than

NEW FEATURES:

• Revolutionary 3D painting and compositing
  Paint
  directly on 3D models, wrap 2D images around 3D shapes, convert gradient

  output with the new ray-tracing rendering engine, and enjoy exporting to
  supported common 3D formats.

• More powerful printing options
  Photoshop CS4 brings
  even higher quality to large, detailed images when taken to print. You can
  now preview out-of-gamut colours and take advantage of a streamlined printing
  interface. In addition, only on Mac OS X for this release, 16-bit printing
  is available for the first time, vastly increasing the colour depth and
  clarity possible in printing.

• Improved Adobe Photoshop Lightroom workflow
  Select
  multiple photos in Adobe Photoshop Lightroom(sold separately) and
  automatically open them in Photoshop CS4 to merge them into a panorama, a
  high dynamic range (HDR) photo, or a multilayered Photoshop document. And
  seamlessly roundtrip back to Lightroom..

• 3D object and property editing
  Edit, enhance, and
  manipulate 3D images in a streamlined interface without dialog boxes. Adjust
  lighting, meshes, and materials. Easily orient objects and position the
  camera using 3D axes and a ground plane.

• Fluid canvas rotation
  Now just click to smoothly
  turn your canvas for distortion-free viewing at any desired angle -- no more
  tilting your head in the middle of painting and drawing.

• Smoother panning and zooming
  Gracefully navigate to
